Abstract
The utility model relates to a heat oxidation device for organic waste gas, which comprises two regeneration beds, wherein each regeneration bed is provided with a gas inlet valve connected with the outlet of a fan; the inlet of the fan is connected with a main waste gas wind pipe; each regeneration bed is provided with a vent valve connected with a chimney; and the regeneration beds are connected with the same burning chamber in which a preheat burner is arranged. Organic waste gas is introduced into the regeneration beds through the fan, the regeneration beds continuously carry out heat release and heat regeneration under the function of switching the valves, i.e. after the valves are opened, one regeneration bed heats the waste gas to certain temperature, so that organic constituents in the waste gas are effectively decomposed; and the other regeneration bed absorbs the heat generated by decomposition to realize the heat regeneration. After the valves are switched, the working functions of the two regeneration beds are interchanged. The surplus heat generated by the decomposition of the organic constituents is recovered by the heat exchanger to be used for other technical processes. The removing rate of the organic constituents in the waste gas is more than 98%, and the utility model can effectively solve the problem of environment pollution of the organic waste gas and simultaneously also can greatly reduce the energy consumption cost in the process of production.

Description of drawings
Fig. 1 is the utility model schematic diagram.
The specific embodiment
Referring to Fig. 1, the utility model comprises technology blower fan 6, two Regenerative beds 1,2.Two pipelines are respectively established in the following or side of Regenerative beds 1,2, and air intake valve 11,21 is established in pipeline connection technology blower fan 6 outlets on the pipeline; Another pipeline connects chimney 7, establishes drain tap 12,22 on the pipeline.The inlet of blower fan 6 is connected with total waste gas airduct 8, on total waste gas airduct 8 waste gas is installed and is inserted valve 81 (according to the quantity of process equipment, this valve can be, also can be several).Fresh airduct 9 also is connected with the inlet of blower fan 6, and fresh airduct 9 is provided with fresh damper 91.Dress ceramic packing in the Regenerative beds 1,2, combustion chamber 5 is located at above two Regenerative beds 1,2, establishes preheat burner 4 on the wallboard; A top or side of combustion chamber 5 is connected with heat exchanger 3 by pipeline, establishes hot bypath valve 31 on the pipeline, and heat exchanger 3 also is connected with chimney 7 pipelines.Also have a control system, be connected in each valve and parts and control.The quantity of each parts of the utility model is not limited to shown in the accompanying drawing, and technology blower fan, preheat burner can have many specifically, and the inlet and outlet valve can have more than four, and Regenerative beds can have more than two.
The utility model has two Regenerative beds, one of them heat exhaust gases, and another then absorbs organic oxidation Decomposition heat in the waste gas and reactivation heat.Regenerative beds can provide waste gas is heated to the needed heat more than 94% of oxidation operation temperature from normal temperature, with the temperature maintenance of combustion chamber between 650-850 ℃, to continue to satisfy the requirement that organic exhaust gas is handled.Heat exchanger can reclaim more than 75% of the unnecessary heat of oxidation operation, thereby reduces production costs greatly.
Below in conjunction with Fig. 1 use of the present utility model is elaborated.
Before the device start, the ceramic packing that Regenerative beds is 1,2 li is in the normal temperature state, at this time needs preheat burner 4 that heat is provided, and the ceramic packing in the Regenerative beds is preheating to the temperature that needs.When equipment was in preheat mode, waste gas inserted valve 81 and closes, and fresh damper 91 is opened, and fresh wind periodically enters Regenerative beds 1 or Regenerative beds 2 by technology blower fan 6.Preheat burner 4 can be to be the burner of fuel with natural gas or liquefier, also can be to be the burner of fuel with diesel oil.When the temperature of Regenerative beds reach temperature required after, waste gas inserts valve 81 and opens, fresh damper 91 is closed, technology blower fan 6 is sent organic exhaust gas to Regenerative beds 1 through the air intake valve of opening 11, Regenerative beds 1 is heated to waste gas the temperature (between 500-800 ℃) that the organic exhaust gas oxidation needs gradually, organic matter in the waste gas then at Regenerative beds 1 top (being in the combustion chamber 5) carry out oxidation Decomposition, absorb and divide analgesic high-temp waste gas to pass through Regenerative beds 2 again, the ceramic packing of this Regenerative beds is carried out heat regeneration, the high-temp waste gas temperature of this moment is minimized, and then entering chimney 7 through the drain tap 22 opened, this gas is the clean cryogenic gas of handling through effectively.Increase along with the time, the temperature of Regenerative beds 1 can reduce gradually, after after a while (in 15 minutes), under the instruction of control system, air intake valve 11 and drain tap 22 are closed, air intake valve 21 and drain tap 12 are opened simultaneously, the waste gas of coming from technology blower fan 6 this moment enters Regenerative beds 2 and by its heating, organic matter in the waste gas is decomposed, absorb the waste gas process Regenerative beds 1 of decomposing heat, with the ceramic packing heat regeneration of this Regenerative beds, EGT reduces simultaneously, enters chimney 7 through drain tap 12.This shows, two pairs of inlet and outlet valve 11,12,21,22 alternately operatings, when the air intake valve 11 that is communicated with Regenerative beds 1 was opened, the air intake valve 21 that is communicated with Regenerative beds 2 was closed, the drain tap 22 that is communicated with Regenerative beds 2 is simultaneously opened, and the drain tap 12 that is communicated with Regenerative beds 1 is closed.By that analogy, vice versa.For Regenerative beds, a heat exhaust gases (waste gas rises to and carries out oxidation Decomposition in the combustion chamber 5) always absorbs heat when another allows the waste gas process and reaches heat regeneration, for waste gas heat oxidation next time ready.
Like this by to advancing, the periodic switch motion of drain tap, organic exhaust gas can be continued to be heated to the temperature that needs, wherein, organic matter can oxidized decomposition in combustion chamber 5. when organic matter decomposes, the temperature of combustion chamber 5 can raise, control system is then closed preheat burner 4, and hot bypath valve 31 opened, unnecessary heat is along with the high-temp waste gas of bypass enters heat exchanger 3, heat exchanger 3 can be with the thermal medium of process requirements (as steam, water, hot blast, the heat conduction wet goods) heating reaches energy-conservation purpose to satisfy the production equipment needs. and hot bypath valve 31 also can in time be opened after combustion chamber 5 preheatings are finished, and utilizes heat exchanger 3 to shift to an earlier date the thermal medium of heating process demand (as steam, water, hot blast, the heat conduction wet goods) to satisfy the production equipment needs.
The utility model is applicable to the processing of various organic exhaust gas.
